I was just reminded of a time when I had just finished 6th grade. My mother told me about it the next day.
She was up late, couldn't sleep. She had stayed up late watching some bad, scary movie called "Picture Mommy Dead." Dad was snoring so was creeped out and couldn't relax. She sat at the top of the stairs with the light on to read so she wouldn't wake Dad.
Suddenly the t.v. downstairs blared to life, when no one was near and it had definitely been off. This was before we had a t.v. with a remote (can you even remember the days??) so it isn't like some random zapper had turned it on. And it was after midnight, so the whole world seemed to be asleep. She went downstairs and turned it off. Now she was really freaking out.
She sat at the top of the stairs again to read and calm down, when I came running down the hallway toward her from my bedroom. She grabbed me and asked me what was the matter. I looked in her eyes and asked really panicked, "Where's Dorothy??" She knew I must be dreaming and took me back to bed.
She gave up and went to bed after that.
I know the exact year this happened because I can still remember that dream. There had been IRL a large tornado through our town that year that had killed 13 people and disrupted my dance recital as a result. I was dreaming about the recital and trying to find everyone when the tornado was coming. My dance teacher was Dorothy. I know it all has Wizard of Oz undercurrents, but when my mom asked me the next morning if I remembered what happened, I told her about my dream but didn't remember getting out of bed or running down the hall.
I have always wondered if there wasn't some poltergeist activity but we never had any other incidents in that house that I know of.
